A DNA-based rewritable memory device

DNA is well known as the genetic material, but has also been used as a building block for the construction of nanoscale structures and periodic arrays. One other application is the storage of information in DNA. Such an information storage method has many advantages including longevity and ability for highly dense storage, and is more suited for archival storage of data. In new work, scientists use shape-changing DNA nanostructures for short term storage of data, where the information is ‘written’ in different conformations of the nanostructures. The stored data can be easily read-out using gel electrophoresis, eliminating any multi-step or costly methods. […]Read More
